  1. 809 Differentiate between adaptive and assistive bioengineered products.

  2. Key concepts/skills: Level 1: Define key vocabulary. Level 2: Differentiate between adaptive and assistive technology. Level 3: Identify examples of biofuels, bioengineered medicines, and bioengineered pest management, and explain why each is either assistive or adaptive technology. Differentiate between adaptive and assistive bioengineered products.

  3. Key vocabulary: Bioengineering Biofuels Bioengineered food Assistive bioengineering Genetic engineering Gene splicing Bioengineered medicine Adaptive bioengineering Pest management Differentiate between adaptive and assistive bioengineered products.

  4. I. Bioengineering • A.The application of engineering to living things such as humans and plants Differentiate between adaptive and assistive bioengineered products.

  5. 1. Assistive Bioengineering • a. engineering that results in a product • or process that helps living • organisms but does not change them • permanently • b. hearing aid, glasses, prosthetic • limbs, band aids Differentiate between adaptive and assistive bioengineered products.

  6. 2. Adaptive Bioengineering • a. engineering that results in a product • or process that changes • living things • b. artificial heart, artificial organs, • cochlear implants Differentiate between adaptive and assistive bioengineered products.

  7. Assistive Bioengineering Adaptive Bioengineering

  8. Bioengineered Products • A. Medicine – good genes or proteins are • manufacture to replace bad ones • using bacteria • 1. Examples- insulin, interferon • 2. Genetic engineering – any change to an • organism’s DNA • 3. Gene splicing – replacing bad or • undesired genes with • working or desired genes Differentiate between adaptive and assistive bioengineered products.

  9. B. In Agriculture – making crops resistant to disease herbicide and frost 1. Herbicide resistant crops (corn) 2. Plants like tomatoes that will ripen on vine and stay fresh longer Differentiate between adaptive and assistive bioengineered products.

  10. C. Biofuels – Ethanol is a clean burning fuel for engines made from plants. 1. Cellulose > sugars > ethanol 2. Bacterium control this process 3. Problem is which plants should be used to make ethanol? 4. Plants used are corn, sugar, sugar beets, switchgrass, algae Differentiate between adaptive and assistive bioengineered products.
